Hybrid lime-pozzolan-geopolymer systems: microstructural, mechanical and durability studies

[EN] This work studies the possibility of using geopolymer materials to enhance the mechanical and durability properties of hydrated lime¿pozzolan mixtures, which gave rise to the so-called ¿hybrid systems¿. Two different waste types were used as pozzolan in the lime¿pozzolan system: rice husk ash (...

Two different waste types were used as pozzolan in the lime¿pozzolan system: rice husk ash (RHA) and spent fluid catalytic cracking (FCC). The geopolymer fabricated with FCC was activated with commercial reagents (NaOH and Na2SiO3), and also with alternative sources of silica to obtain a lower carbon footprint in these mixtures. The alternative silica sources were RHA and residual diatomaceous earth (RDE) from the beer industry. The geopolymer mixture substituted the lime¿pozzolan mixture for 30% replacement in weight. The hybrid systems showed better mechanical strengths for the short and medium curing ages in relation to the lime¿pozzolan mixtures. Thermogravimetric analyses were performed to characterise the types of products formed in these mixtures. In the durability studies, hybrid systems better performed in freeze¿thaw cycles and obtained lower capillarity water absorption values.This research forms part of a project supported by MINECO and FEDER funds (ECOSOST RTI2018-097612-B-C21-AR).MDPI AGDepartamento de Ingeniería de la Construcción y de Proyectos de Ingeniería CivilEscuela Técnica Superior de Ingeniería de Caminos, Canales y PuertosInstituto Universitario de Investigación de Ciencia y Tecnología del HormigónAgencia Estatal de InvestigaciónEuropean Regional Development FundMinisterio de Economía y CompetitividadMinisterio de Asuntos Económicos y Transformación DigitalRepositorio Institucional de la Universitat Politècnica de València Riunet20222022-04-08journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://riunet.upv.es/handle/10251/192627reponame:RiuNet.
